Envelope reconstruction of speech and music highlights stronger tracking of speech at low frequencies
Fig 4
(A) Model weights, median across subjects and averaged across channels. Models are color-coded based on their frequency range (see to the right of the plots). The model of the range 0.0625–0.5 Hz was excluded because none of the stimuli exhibited significant neural tracking in this range, and the large values for the weights obscured the trends in the other models. (B) Mean and standard error across subjects of model weights for two frequency ranges (see S9 Fig for the models for individual subjects). (C) and (D) show the topographies of the model weights averaged over the range of delays corresponding to peaks and troughs in the 4–32 Hz and 0.5–4 Hz models respectively. Note that the range of delays vary across stimulus types in the 4–32 Hz model in order to capture similar peaks and troughs.
